Crystal analysis of demineralization and remineralization mechanism of dental enamel

本研究的目的是将脱矿和再矿化牙釉质的矿化度评价与晶体结构分析进行比较。标本用膜过滤器包裹的釉质粉末制备而成。样品用CMR测定矿物质损失，用FTIR和TEM分析晶体结构。本研究结果显示，在CMR评价无显著差异的情况下，再矿化牙釉质与完好牙釉质的晶体结构存在差异。本研究采用矿化度评价与晶体结构分析相结合的方法，确定了再矿化时间为4周。结论：无论是矿物级评价还是晶体结构分析，对釉质脱矿和再矿化的评价都是非常重要的。

The aim of this study is to compare mineral level evaluation with crystal structure analysis of demineralized and remineralized enamel. The specimens were prepared with powdered enamel enclosed by membrane filter. The specimens evaluated mineral loss by CMR and analyzed crystal structure by FTIR and TEM. The results of this study, when there was no significant difference by CMR evaluation, the crystal structure of remineralized enamel and sound enamel was different. The method of this study which was compared mineral level evaluation with crystal structure analysis was appropriate for keeping 4 weeks remineralization time. It was concluded that it is important for evaluate of demineralization and remieralization of enamel, not only use mineral level evaluation but also crystal structure analysis.
